To all whom; it may concern: y

Be it known that I, 'GEORGE H. SHANE, a citizen of the United States, residin in the city and county of Denver and tate of Colorado, have invented certain new and useful Improvements in Insulating Means for Railway Ties and Chairs; and I do dc-v clare the following to be a full, clear, and exact description of the invention, such as ill ena-ble others skilled in the art to which 1t appertains to make and'use the same, referencebeing had to the accompanying drawings, and tothe letters and figures of reference marked thereon,which form a part of this specification.

yinvention relates to improvements in insulating means for railway ties and chairs of the nature claimed and described in latent.`No. 894,072, issued to Robert E. Foresman and myself, July 21, 1908,. and in my application, Serial No. 728,970, filed November 1, 1912. s

present invention is to for insulating the tie from the chair and the chair from the rail, where utilize one or both of the as in block signaling systems, or on electric roads.

Another object is to provide a construe tion in which the insulation shall be lof such form that it will be impossible to assemble it improperly whereby-the employment of high grade labor will be unessential.

ther objects will appear hereinafter as I proceed with the description of that enibodiment of the invent-ion which for the purposes of the resent application, I have illustrated in t e accompanying drawing, in which:

Figure 1, is a plan view of a section of means; Fig. 2, is a view partly in section upon the line 2 2, Fig. 1, looking in the direction of the arrow. Fig. 3, is a section taken upon the line 3 3, Fig. 1, looking in the direction of the arroi Fig. 4, is a sectionaldetail of an insulating sleeve' employed in my invention. Fig. 5, is a det-ail in perspective of a rail casing of insulating?` isa view in perspective of one form of the .main insulatingmember.

7, is a Similar view showing oneof a Fig.

-pair of insulating members which may be employed instead of the 'single member of place.

Fig; 6. Fig. 8, is a similar view of a modifih cation.

Similar reference numerals refer to like parts throughout the views.

In the drawing which forms a part of this specification the numeralv 5, designates a tie .of channel iron, the side iinnges of which are 'cut away at 6, forming rectangular recesses therein which constitute seats or heal`- members 7, depressed throu li vout their middle portions 8, to fit into ,t e recesses G thereby preventing movement of the insulation members lonvitudinally of the ties. .Eachinsulation mem er 7, is provided at its'sides with depending flanges 9,'wliicli are arranged to embrace the opposite sides ofthe tie.

In the preferred forni of insulation memn berillustrated in Fic' 6 the depressed p0rtion 8, is interrupted centrally by a pocket made integral with the portion 8, and extending for the full length of that portion in a direction parallel to the side tlnn es 9. The pocket 10, is made of' the proper depth to rest upon the base of thetie 5, when the insulation member is in place as clearly illus-` trated-in'Fig. 2.

The differentparts of the modification of Fig. -7, are precisely similar to those of Fig. 6 and will not require further description. It .may be advantageous to construct theirn sulation member in two parts as indicated at Fig. 7, especially where it is! desired to apply tho insulation to tracks! already in About the bottom of the rail 11, I locate an insulating casing 12, which is approximately as long as the tie is wide, one of these easingrs being; positioned upon the rail above each tie. Rail chairs 13, made in two parts and having central depending ribs ,14, are mounted upon' the insulation members?, the ribs 14 ittinginto the pockets 10, of the members 7, and the lower surfaces of the chairs haviinT shoulders 15, adapted to engage against the ,ends of the depressed portions 8. The chairs ,13, are also provided with depending side fia'ngcs 16, which overlap the flanges 9, of the insulation members. lVhen the parts are in position insulation sleeves 17, having;r enlarged heads 18, are forced through alining openings in the iianges 16,' and 9, andl side flanges of the tie 5. Insulation sleeves 19 are also forced through alining openings in the ribs 14' and side wallsbf the pockets 10. Then by the
